Justification:
The distribution of P. bellei is limited and is known from only nine counties in three states. The sandy lakes and sandy spring-fed streams that comprise its habitat are vulnerable to development and logging. The species has been found at fewer than ten locations in recent years.

Development of lakes and woodland in parts of range, quite possible in the regions not currently under protection, is likely to decrease viable habitat in the future. Small streams and shallow lakes are liable to dry out with potential drought from global warming.

P. bellei is present in some national forests but not in completely protected areas. National forests are unlikely to be developed. Research into all aspects of its biology and identification of more protected areas are needed.
